Anthropology and EE major Jack Andraka
May 2018

Jack Andraka, a junior in anthropology and electrical engineering has been awarded the 2018 Truman Scholarship for Graduate Studies. He plans to put his training in engineering, anthropology and data science to work as a public health physician devoted to addressing global health inequities affecting citizens in low- and middle-income countries.

Jack is one of 59 exceptional college students chosen from across the nation for the scholarship, which provides up to $30,000 for graduate study – in the United States or abroad – to students who want to attend graduate school in preparation for a career in public service.

Andraka's honors thesis in anthropology focuses on Sierra Leone: Disease Dollars: An Ethnographic Study of Foreign Aid and Ebola in Sierra Leone. Andraka hopes to study how environmental contaminants violate the health and human rights of disadvantaged populations in the impoverished West African country.

He is also writing an honors thesis in electrical engineering, A Novel Paper Biosensor for the Detection of Infectious Diseases and Environmental Contaminants, which describes the sensors he developed that detect 20 different diseases or contaminants in five minutes at a cost of less than one cent.

As a Truman Scholar, Andraka intends to enter an MD/MPH (Doctor of Medicine/Master of Public Health) program specializing in global health.

"The MD degree would enable me to frame my engineering background within medicine and provide me with an appreciation for the clinical realities of working in global health," Andraka wrote in his Truman Scholarship application. "In doing so, I will be able to work with communities in clinical settings to better understand locally relevant issues and design programs to address them. The Master of Public Health degree, alongside my anthropology training, will provide me with a deep understanding of broader socioeconomic, environmental and political determinants of health."

Eventually, Andraka hopes to become a public health physician devoted to addressing the global health inequities in low- and middle-income countries, where life expectancy is 36 years lower than in high-income countries.

Please join us in congratulating Jack on his excellent achievement!

Emeritus professor James Gibbons
May 2018

Congratulations to emeritus professor Jim Gibbons! Recognized by Avenidas for his significant contributions in the social well-being of the community at large.

"[...T]he former Dean of the School of Engineering at Stanford, is known internationally for his important achievements in education and for his development of fabrication technologies that were foundational for the modern semiconductor industries in Silicon Valley and around the world. Less well known is the fact that his work has also contributed significantly to the social well-being of our community at large. Jim also served on no less than 13 boards in the Valley (among them Cisco, Raychem, SRI, Lockheed Martin, PARC, and more). In the educational field, he vastly expanded and improved the Stanford Instructional Television Network, which provided topnotch education via television to thousands of engineers at local companies. Again, this provided a crucial piece of "infrastructure" to the Valley, and was a forerunner of present internet courses.

His engagement with the Santa Clara Juvenile Hall in 1996 led him and his colleagues at SERA Learning to develop a successful program that teaches at-risk youth how to manage their anger and walk away from fights. SERA's "Skills for Managing Anger" course has since be used in 355 schools and juvenile justice applications across the country, including Columbine High School and NYC after 9 /11. It included new student centered teaching methods that Jim had developed for the Stanford Video program. Jim credits his wife Lynn who supported him in all his endeavors. He says: "She encouraged me to do things that would serve the needs of others." Avenidas is thrilled to celebrate Jim's amazing contributions and success."

The 2018 Lifetimes of Achievement honorees include Nancy Mueller, Dick Mansfield, Ellie Mansfield, Kristine Erving, John Erving, Christy Holloway and Jim Gibbons.

Angad Rekhi (PhD ’20), Allen Building, Stanford EE
April 2018

Come to the Allen Building and view the original wall art designed by EE PhD candidate Angad Rekhi.

Angad Rekhi has spent many hours in the Allen Building, researching & reflecting on low power circuits and systems. As a member of the Arbabian Lab, he also helped develop a low power wake up receiver for IoT.

Angad was intrigued by the call to submit a design for the Allen Building entrance. The design challenge opened in October 2017, encouraging students, faculty & staff to create a visually representative piece that illustrates the research done within the Allen Buildings.

Angad's concept illustrates the entire electrical engineering design hierarchy – from a device-focused perspective at the far left, through chip and board design in the center, to end applications on the far right. "Design at all levels occurs in the Allen Buildings. They contain spaces and labs for the full process of design and build, from concept to product," states Angad. "For example, ExFab allows rapid prototyping of microelectronics, and the SPF (System Prototyping Facility) supports electronic sub-system design. So really, anyone on campus can go from idea to product within these walls."

Angad Rekhi (PhD ’20) posing with his wall design in the Allen Building

Please come by to view Angad's artwork!
The wall art is a creative way to greet those interested in leveraging Allen's spectrum of device development, and those who are yet to discover what's possible inside of the Allen Buildings.

About the Allen Buildings
At the time of it's construction, the building (originally named CIS) was considered "the best example of Stanford's resident architect's progressive historicism," acknowledging the blending of 1880s architectural style with 20th and 21st century Stanford architecture. The "building was designed by Antoine Predock, an Albuquerque architect with a reputation for New Age structures that rise organically from the Southwest's desert landscape." The building is named after Microsoft's co-founder, Paul G. Allen.

Together, the Allen and Gates buildings anchor the north side of the Engineering Quad. Twenty years ago, former Dean James Gibbons said "It has been a 10-year dream of ours to draw electrical engineering and computer science – the hardware and the software ­– together in an environment surrounded by such things as the biological sciences and medicine." And by spring 2019, the Neurosciences and ChEM-H research facility is expected to be complete, just on the north side of the Allen Buildings.

Nikhil Garg, EE PhD '20 interdisciplinary research using machine-learning
April 2018

Lead author Nikhil Garg (PhD candidate '20) demonstrates that word embeddings can be used as a powerful tool to quantify historical trends and social change. His research team developed metrics based on word embeddings to characterize how gender stereotypes and attitudes toward ethnic minorities in the United States evolved during the 20th and 21st centuries starting from 1910. Their framework opens up a fruitful intersection between machine learning and quantitative social science.

Nikhil co-authored the paper with history Professor Londa Schiebinger, linguistics and computer science Professor Dan Jurafsky and biomedical data science Professor James Zou.

Their research shows that, over the past century, linguistic changes in gender and ethnic stereotypes correlated with major social movements and demographic changes in the U.S. Census data.

The researchers used word embeddings – an algorithmic technique that can map relationships and associations between words – to measure changes in gender and ethnic stereotypes over the past century in the United States. They analyzed large databases of American books, newspapers and other texts and looked at how those linguistic changes correlated with actual U.S. Census demographic data and major social shifts such as the women's movement in the 1960s and the increase in Asian immigration, according to the research.

"Word embeddings can be used as a microscope to study historical changes in stereotypes in our society," said James Zou, a courtesy professor of electrical engineering. "Our prior research has shown that embeddings effectively capture existing stereotypes and that those biases can be systematically removed. But we think that, instead of removing those stereotypes, we can also use embeddings as a historical lens for quantitative, linguistic and sociological analyses of biases."

"This type of research opens all kinds of doors to us," Schiebinger said. "It provides a new level of evidence that allow humanities scholars to go after questions about the evolution of stereotypes and biases at a scale that has never been done before."

"The starkness of the change in stereotypes stood out to me," Garg said. "When you study history, you learn about propaganda campaigns and these outdated views of foreign groups. But how much the literature produced at the time reflected those stereotypes was hard to appreciate." 

The new research illuminates the value of interdisciplinary teamwork between humanities and the sciences, researchers said.

"This led to a very interesting and fruitful collaboration," Schiebinger said, adding that members of the group are working on further research together. "It underscores the importance of humanists and computer scientists working together. There is a power to these new machine-learning methods in humanities research that is just being understood."

Paper Summary:

Internet companies such as Facebook and Google host trillions of messages, photos, and videos for their users. Hence, they need storage systems that are massive in scale, fast to access, and cost effective. Scale is achieved by hosting internet services in datacenters with thousands of machines, each contributing its local storage to the global data pool. Speed is achieved by selectively replacing slow hard disks in machines with Flash storage devices that can serve data accesses with 100x lower latency and 10,000x higher throughput.

However, Flash makes it difficult to build a cost-effective storage system. Flash devices are typically underutilized in terms of capacity and throughput due to the imbalance in the compute and storage requirements of the internet services running on each machine. In the past, datacenter operators dealt with the same challenge for disks by allowing services running on each machine to allocate storage over the network on any disk with spare capacity and bandwidth in the datacenter. Remote (over the network) access to disks enables utilizing all available capacity and throughput. Past efforts to implement similar remote access systems for Flash devices have run into significant challenges. Network protocol processing at the throughput of Flash devices requires a large number of processor cores and adds overheads that cancel out the latency advantages of using Flash. Moreover, when two remote machines access the same Flash device, interference between the two access streams can lead to unpredictable performance degradation.

To address these challenges, researchers Ana Klimovic, Heiner Litz and Christos Kozyrakis developed a software system called ReFlex. ReFlex enables high performance access to remote Flash storage with minimal compute resources and provides predictable performance for multiple services sharing a Flash device over the network. Using a single processing core, the system can process up to 850,000 requests per second which is 11x more than a traditional Linux network storage system. ReFlex makes remote Flash look like local Flash to applications, making it easy for a service running on a particular machine to use spare Flash capacity and bandwidth on other machines in the datacenter. To provide predictable performance when multiple remote machines access the same Flash device, ReFlex uses a novel scheduler to process incoming requests in an interference-aware manner.

ReFlex is having an increasing impact in industry and, in collaboration with IBM Research, has been integrated into the Apache Crail distributed storage system. This integration allows popular data analytics frameworks to leverage ReFlex to improve their resource efficiency while maintaining high, predictable performance. ReFlex is also being ported to a system on chip (SoC) platform by Broadcom Limited. ReFlex is open-source software and available at: https://www.github.com/stanford-mast/reflex.
